One area of ecological benefit not yet fully evaluated... is the utilisation of restored saltmarsh habitats by fish species.... Factors affecting habitat of managed realignments and fish populations [were studied. ] Each microhabitat was [examined] as a function of the extent of fish colonisation. A positive relationship between the degree of fish utilisation and habitat heterogeneity was ascertained using species richness, abundance and behavioural observations. 2, record 1, English, - fish%20utilization

La méthode des microhabitats a pour objectif de quantifier, en fonction du débit, l'évolution de l'habitat physique de la rivière pour des poissons dont on connaît les exigences ou les préférences biologiques. En d'autres termes, cette méthode permet : a) de donner à un tronçon de cours d'eau une valeur potentielle d'habitat à partir des critères morphodynamiques : hauteur, vitesse, substrat, en incluant les variations de débits, b) de déterminer quelle est la valeur optimale de débit pour le «bien-être» d'une espèce à un stade de développement, c) de prévoir ou de simuler différents scénarios de gestion hydraulique des cours d'eau, notamment pour répondre à la question des débits réservés. 3, record 4, French, - m%C3%A9thode%20des%20microhabitats

La méthode des microhabitats a été définie dans ses grands principes par Waters (1976), puis améliorée et informatisée par Bovec (1982), aux États-Unis, sous la dénomination de «Instream Flow Incremental Methodology» ou IFIM. La méthode IFIM permet de prédire la quantité d'habitat disponible d'une portion de cours d'eau en fonction de différents paramètres retraçant les conditions hydrodynamiques. Le module principal consiste en une «simulation physique de l'habitat» selon la dénomination anglo-saxonne : Physical HABitat SIMulation ou PHABSIM [...]. Depuis 1985, une méthode semblable a été développée par le Laboratoire d'Hydroécologie Quantitative du CEMAGREF et adaptée aux cours d'eau français [...] 2, record 4, French, - m%C3%A9thode%20des%20microhabitats

Numerical Habitat Models(NHM) have been developed to predict fish habitat quantity, quality and distribution under different flow regimes found in rivers. These models depend on the estimation of an Habitat Quality Index(HQI) at the scale of fish microhabitat. One of the problems of NHM is that mathematical constructs to estimate HQI in one river may not be applicable to other rivers. Hence, HQI are not transferable among rivers. The most common measures of HQI are based on indices of preference of fish for specific ranges of water depth, current speed and substrate composition(referred to as Habitat Suitability Indices; HSI). 5, record 5, English, - habitat%20quality%20index

Inspiré du «Habitat Suitability Index (HSI)», élaboré aux États-Unis, l'indice de qualité de l'habitat (IQH) est un modèle mathématique qui permet d'évaluer, pour une espèce faunique, la valeur en tant qu'habitats (milieu dans lequel une espèce animale donnée trouve, en quantité suffisante, les éléments biologiques et physiques nécessaires à sa survie et à sa reproduction) d'une série de peuplements forestiers. L'IQH ne sous-entend pas une certaine densité de population pour chaque classe d'habitat, c'est-à-dire que l'IQH ne donne pas une projection de la densité d'individus possible que l'on peut trouver dans un peuplement, mais il détermine la valeur de ce peuplement en termes d'habitats pour certaines espèces. 1, record 5, French, - indice%20de%20qualit%C3%A9%20de%20l%27habitat
